The TP MG90 Metal Gear sub micro servo is a great choice when you need the extra torque and security of metal gears. This servo is similar in size to the TP SG90 and Hitec HS-55, but provides nearly much more torque. The TP MG90 has the universal "S" type connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum and Hitec.
